I want to make SharePoint List with all users computer info, instead of manually go to each PC in our company, how can I retrieve their PC info, Including mac address which what I want most for networking troubleshooting.
Unfortunately not. You would need an agent (application) on the computer that pushed this information to the SharePoint list. The browser does not have these details as it would be a potential security risks.
I would suggest another tool, i.e. InTune, ServiceNow, or some other tool that specializes in computer asset management.
You will need a different approach than SharePoint. This might be a direction to investigate, using PowerShell: https://shellgeek.com/powershell-get-computerinfo BTW: The output of course could very well be written to a SharePoint List
